Credit Card

If you must prepay, please use a valid credit card. USP accepts Visa, MasterCard, and American Express. Credit cards are the easiest payment method. Do not send checks or wire transfers if prepaying your order.

Official USP Price Quote

If you are prepaying your order, get an official USP price quote before ordering. Having an official USP price quote allows you to complete your credit card payment with the security of knowing the price will not change until a specified date. 

Customs Clearance

USP does not offer customs clearance services. We suggest that you arrange for a customs broker to facilitate clearance or allow FedEx to clear customs for you. Customs clearance is often the longest part of your product delivery time. Customers are responsible for paying all customs duties, taxes, or tariffs levied for bringing USP products into your country.
